Bazooka, isoform B; Bazooka (baz) encodes a scaffold protein that forms a complex with the products of par-6 and aPKC and with other cortical, cytoskeletal and regulatory proteins. It functions in cell polarization pathways in epithelial, neuronal and other cell types.

Kinase suppressor of ras (ksr) encodes a MAP-kinase scaffold protein. It mediates the activation of the serine/threonine kinase encoded by Dsor1.

Dual specificity mitogen-activated protein kinase kinase dSOR1; Required downstream of Raf in the sevenless (sev), torso (tor), and Drosophila EGF receptor homolog (DER) signal transduction pathways. Involved in both positive regulation (at the posterior terminus) and negative regulation (at the anterior domain) of tll, as in other terminal class gene products, maybe via the ERK-A kinase. Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.

Raf homolog serine/threonine-protein kinase Raf; Serine/threonine kinase required in the early embryo for the formation of terminal structure. Also required during the proliferation of imaginal cells. May act downstream of Ras85D in the tor signal transduction pathway. During larval development, mediates Ptth/tor signaling leading to the production of ecdysone, a hormone required for the initiation of metamorphosis. Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. RAF subfamily.

Tyrosine-protein kinase Src42A; Required directly or indirectly for the phosphorylation of drpr which is necessary for the interaction of drpr with shark and subsequent glial phagocytic activity. Together with drpr and shark, promotes the migration of macrophages to sites of wounding as part of a signaling cascade where Scr42a detects production of hydrogen peroxide at wound sites which triggers phosphorylation of drpr and subsequent recruitment and activation of shark. Essential for correct eye morphogenesis (ommatidial R7 neuron formation) which requires the Ras1/MAPK signal transduc [...]

Connector enhancer of KSR protein CNK; Enzyme regulator activity; MAP-kinase scaffold activity; receptor tyrosine kinase binding; mitogen-activated protein kinase kinase kinase binding; protein binding.

Protein aveugle; Required for normal photoreceptor differentiation between Ras and Raf for EGFR signaling in the eye and for mitogen-activated protein kinase phosphorylation. Probably acts together with Cnk to promote Raf activation, perhaps by recruiting an activating kinase.

Atypical protein kinase C; Serine/threonine protein kinase which is required for apico- basal cell polarity in the germ line as well as in epithelial and neural precursor cells, for epithelial planar cell polarity and for cell proliferation. During oocyte development, required for the posterior translocation of oocyte specification factors and for the posterior establishment of the microtubule organizing center within the presumptive oocyte. Phosphorylates l(2)gl which restricts l(2)gl activity to the oocyte posterior and regulates posterior enrichment of par-1, leading to establishmen [...]

Maternal effect protein oskar; Organizes the germ plasm and directs localization of the posterior determinant nanos. Oskar protein is required to keep nos RNA and staufen protein at the posterior pole.
